I want my phone to broadcast wifi without being connected to internet

something that's been stumping me is how to do peer to peer, mobile to mobile file transfering from my android phone's files TO my playbook tablet without being connected to the internet. Tried bluetooth methods already so that route is a no-go as well. I was hoping there was some way to turn my android phone into a wifi server on its own without needing the internet. kind of like what the Goflex Sattelite portable hard drive does.

omg I searched this for days and the solution was in my face the entire time. as foolish as i feel for missing the totally obvious I'm amazed that so many search results said it wasn't possible. thank you so much!
